- Dairy cow mortality is an important animal welfare issue that also causes financial losses. The objective of this study was to identify farm characteristics and herd management practices associated with high on-farm cow mortality in Swedish dairy herds. A postal questionnaire was sent to farmers that had either high or low mortality rates for 3 consecutive years. The questionnaire consisted of five sections: 'About the farm', 'Milking and housing', 'Feeding', 'Routines' and 'Lame and sick cows'. A total of 145 questionnaires were returned (response rate = 33%). Ten of the 77 characteristics investigated met the inclusion criteria for multivariable analysis. The final logistic regression model included: herd size, breed, use of natural service bull, bedding improvement frequency and pasture system. Herds with Swedish Holstein as the predominant breed (odds ratio (OR) 22.9, 95% confidence interval (CI) 5.2 to 101.8) or with mixed breeds (OR 5.5, 95% CI 1.7 to 17.5) had a greater risk of being high mortality herds than herds that were predominantly Swedish Red (OR 1). Herds larger than 100 cows (OR 19.6, 95% CI 3.5 to 110.4) and herds with 50 to 99 cows (OR 13.8, 95% CI 3.2 to 60.6) had greater risk of mortality than herds numbering 35 to 50 cows (OR 1). Being a high mortality herd was also associated with having cows on exercise lots during the summer season (OR 3.6, 95% CI 1.3 to 9.9) compared with on pasture. A missing answer on the question of bedding improvement frequency was associated with high mortality herds. Overall, this study suggests that characteristics that are related to intensification of the dairy industry are also associated with high on-farm mortality of dairy cows.

- An increase in on-farm mortality (euthanasia and death) in dairy herds has been reported in several countries in the last decade. This does not only imply possible problems with animal welfare, but it also causes economic losses to the farmer. The objective of this study was to evaluate time trends in on-farm dairy cow mortality in Sweden and identify potential herd-level risk factors. Data were retrieved on all Swedish dairy herds enrolled in the milk recording scheme between 2002 and 2010. Herds with a herd size of <20 cows or a mortality rate (MR) of >40 dead or euthanized cows per 100 cow-years were excluded. Two different models were used: 1 multiple-year analysis, which included 6,898 herds during the period 2002 to 2010 and 1 single-year analysis including 4,252 herds for the year 2010, where other variables that were not present during the entire multiple year study were analyzed. The outcome variable was the number of euthanized and dead cows per year and season. A negative binomial regression model, adjusted for clustering within herd, was applied to both models. Fixed effects in the multiple-year analysis were breed, calving interval, herd size, milk yield, region, season, pasture period, and year. The fixed effects in the single-year analysis were breed, calving interval, conventional versus organic farming, herd size, housing system, milk yield, region, and season. The results demonstrated that MR gradually increased from 5.1 to 6.6 events per 100 cow-years during the study period. Swedish MR are consequently on par with, or even greater than, MR among dairy herds in other comparable countries. Higher mortality was associated with larger herd size, longer calving intervals, and herds that had Swedish Holstein as the predominant breed. Lower mortality was observed in herds with a higher herd average milk yield, during the fall and winter, and in organically managed herds. There were regional differences in mortality. An interaction between herd size and season was found in both models. Also, an interaction between housing system and milk yield was found in the single-year analysis. This first assessment of on-farm mortality in Swedish dairy herds confirmed that the MR has increased over the last few years. The study also identified some herd-level risk factors.

Tidskriftsartikel (refereegranskat)abstract
- Dairy cow mortality (unassisted death and euthanasia) has increased, worldwide and in Sweden. On-farm mortality indicates suboptimal herd health or welfare and causes financial loss for the dairy producer. The objective of this study was to identify cow-level risk factors associated with on-farm cow mortality. Cows with at least one calving between 1 July 2008 and 30 June 2009 from herds enrolled in the Swedish official milk recording scheme with >40 cow-years were included. Each cow was followed from the day of calving until she calved again or left the herd (died, slaughtered or sold). The effects of potential risk factors on on-farm cow mortality were analysed using a Weibull proportional hazard model with a gamma distributed frailty effect common to cows within herd. The event of interest (failure) was euthanasia or unassisted death. An observation was right censored if the cow was slaughtered, sold, calved again or had an on-going lactation at 500 days after calving. The lactations were split into seasons (January to April, May to August and September to December) and at 30 and 100 days in milk in order to evaluate seasonal effects and the effect of disease in different lactation stages. Primiparous and multiparous cows were analysed separately. The highest hazards for both primiparous and multiparous cows were found for traumatic events and diseases, both in the lactation stage in which the cow died and in the preceding stage. The hazard was higher in early lactation and lower in 2nd parity compared to higher parities. Increased age at first calving (for primiparous cows), calving between January and April, dystocia and stillbirth also increased the mortality hazard. Differences were also found between breeds, between milk production parameters at first test milking and between management types. The results from this study show the importance of good management and preventive health actions, especially around calving, to avoid mortality in dairy cows. (C) 2014 Elsevier B.V.

Tidskriftsartikel (refereegranskat)abstract
- It is well known that people with severe mental illness have a reduced life expectancy and a greater risk of being affected by preventable physical illnesses such as metabolic syndrome, cardiovascular disease and type 2 diabetes. There are still, however, only a few published studies focusing on what enables healthy living for this group. This study thus aimed to describe what enables healthy living among people with severe mental illness in psychiatric outpatient services. The data were collected in qualitative interviews (n=16) and content analysis was used to analyze the data. The interviews resulted in an overall theme Being regarded as a whole human being by self and others, which showed the multidimensional nature of health and the issues that enable healthy living among people with severe mental illness. Three categories emerged: (i) everyday structure (ii), motivating life events and (iii) support from significant others. The results indicate that a person with severe mental illness needs to be encountered as a whole person if healthy living is to be enabled. Attaining healthy living requires collaboration between the providers of care, help and support. Health care organizations need to work together to develop and provide interventions to enable healthy living and to reduce poor physical health among people with severe mental illness.

Health among people with psychotic disorders and effects of an individualized lifestyle intervention to promote health
- 2020

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The overall aim of the thesis was to increase knowledge of health among people with psychotic disorders such as schizophrenia and other long-term psychotic conditions. The aim was also to investigate health effects, in terms of clinical health outcomes and self-reported questionnaires, of atwo-year individualized lifestyle intervention implemented in psychiatric outpatient services involving cooperation with the municipal social psychiatry services. The motivation for the study was to generate new knowledge in order to be able to promote health in people with psychotic disorders and to improve the care and support provided for this target group. The thesis consists of four studies. A quantitative study (Study I), was conducted using a cross-sectional design to investigate the prevalence of overweight, obesity, risk of cardiovascular disease (CVD) and the relationships between self-rated salutogenic health, sense of coherence, CVD risk, and body mass index among people with psychoticdisorders (n=57). The study was conducted in four psychiatric outpatient services; questionnaires were completed by the participants and clinical health measurements were collected by the participant’s contact nurse at the psychiatric outpatient services. The participants showed a moderate/high risk of CVD, the mean for BMI was 31.9 (59.6% were obese) and 31.6% were overweight. The results did not reveal any relationships between the subjective and objective measuresof health indicating the need for both subjective and objective assessments of health in psychiatric care. In a qualitative study (Study II), data were collected with semi-structured interviews (n=16) andanalyzed with qualitative content analysis. The interviews resulted in an overall theme “Being regarded as a whole human being by self and others”, which showed the multidimensional nature of health and the issues that enable healthy living among people with severe mental illness. Three categories emerged: (i) everyday structure (ii), motivating life events and (iii) support from significant others. The results indicate that a person with severe mental illness needs to be encountered as a wholeperson if healthy living is to be enabled. In a quasi-experimental study (Study III), the potential effects of participation in the two-year lifestyle intervention (intervention group n=54 and control group (n=13) were investigated. The data were collected at baseline, after 12 months and after 24 months using the self-reported questionnaire the Salutogenic Health Indicator Scale (SHIS), the Hopkins Symptom Checklist (HSCL-25) and the National Public Health Survey. Measures of clinical healthoutcomes were conducted by the participant’s contact nurse at the psychiatric outpatient services. Multilevel modeling was used to test differences in changes over time. Significant changes were foundin physical activity, HbA1c and waist circumference after participation in individualized lifestyle intervention. The relationship between changes in physical activity, levels of salutogenic health and glycated hemoglobin (Hb1Ac) were investigated (n=54) in Study IV. The data were collected atbaseline, after 12 months and after 24 months using the self-reported questionnaires Salutogenic Health Indicator Scale (SHIS) and National Public Health Survey. Within-person changes in physical activity between baseline and at the end of the twenty-four-month intervention were calculated. Selfreported increased physical activity was positively associated with self-rated salutogenic health and negatively associated with level of HbA1c after participation in the intervention. The thesis shows that a well-founded assessment of general health needs must consider both the individual's subjective experiences and objective measurements in order to form a solid foundation for dialogue and shareddecision-making about essential care services. The results also show that it is possible to stimulate healthy behavioral changes with a two-year individualized lifestyle intervention and bring both subjectively and objectively measured health benefits for people with psychotic disorders. The importance of nurses in psychiatric care applying a holistic approach and integrating lifestyle interventions into daily person-centered psychiatric care in collaboration with other healthcare providers to facilitate changes towards a healthy lifestyle in persons with psychotic illness is emphasized in the thesis.

- People with psychotic disorders experience to a great extent avoidable physical illnesses and early mortality. The aim of the study was to investigate the potential effects for this group of participating in a lifestyle intervention. A multi-component nurse-led lifestyle intervention using quasi-experimental design was performed. Changes in biomedical and clinical measurements, self-reported health, symptoms of illness and health behavior were investigated. Multilevel modeling was used to statistically test differences in changes over time. Statistically significant changes were found in physical activity, HbA1c and waist circumference. A lifestyle intervention for people with severe mental illness can be beneficial for increasing physical activity.

- Life expectancy is greatly reduced in patients with schizophrenia, and cardiovascular diseases are a leading cause of mortality. The aim of this cross-sectional study was to investigate the prevalence of overweight, obesity, and cardiovascular disease (CVD) risk and to investigate the relationships between self-rated health, sense of coherence, CVD risk, and body mass index (BMI) among people with severe mental illness (SMI) in psychiatric outpatient settings. Nearly 50% of the participants were exposed to moderate/high risk of CVD and over 50% were obese. The results showed no statistically relationships between the subjective and objective measures (Bayes factor <1) of health. The integration of physical health into clinical psychiatric nursing practice is vital.

Konferensbidrag (refereegranskat)abstract
- Background: Over the previous decades, scientific research has demonstrated that people with persistent mental illness like schizophrenia and other psychotic disorders have a reduced life expectancy and have a higher risk of being affected of preventable physical illnesses such as developing metabolic syndrome, cardiovascular disease and type 2 diabetes. Additionally it have made evident for lower quality of life as well. These risk factors make health promoting essential in the care providing and therefore it ́s important for the health professionals to have a deeper knowledge about the facilitating factors to healthy living described by persons themselves.Aim: The aim of this qualitative study was to describe the experiences of persons affected by persistent mental illness such as schizophrenia or other psychotic disorders what facilitates healthy living in their everyday life. The presentation has the focus on the facilitative factors applying health professionals when providing care for persons in psychiatric out-patient settings.Method: The study was carried out in three different psychiatric out-patient settings in the southern Sweden. The data was collected through qualitative interviews (N= 16) and analyses by qualitative, inductive approach abased on Granheim and Lundmans ́ conceptualization of content analysis.Results: First, it is essential for persons with persistent and severe mental illness that they get support to bring out their needs to healthier living by having a dialogue about the issues of healthy living in their everyday life. In this dialog they may also need support to reflect and find out their own motivating factors to healthier living. Additionally, in this dialogue it is important to be aware of that they will be regarded as a whole person and include many areas of life like daily structure and social life. The professionals should show a truly involvement and active interest to persons when increasing healthy living.Conclusion: Many persons with persistent mental illness need practical support in their everyday life to maintaining healthier living. This requires the close cooperation between psychiatric out-patient settings, the housing support professionals from municipalities and the social services.
